Insights
Fasting, particularly during Ramadan, was associated with a higher incidence of cerebral venous and sinus thrombosis. Susceptible individuals may face increased risks, warranting further investigation into this fasting-related health concern.
Area of Science:
- Neurology
- Vascular Medicine
- Public Health
Background:
- Cerebral venous and sinus thrombosis (CVST) is a rare but serious condition.
- The impact of fasting on CVST incidence is not well-established.
- Previous studies suggest fasting may not increase arterial stroke risk.
Purpose of the Study:
- To investigate the association between fasting periods and the occurrence of cerebral venous and sinus thrombosis.
- To compare the frequency of CVST during fasting months versus non-fasting months.
Main Methods:
- A retrospective study of 162 patients with CVST from 2001-2006 in Isfahan.
- Patients were categorized into two groups: onset during fasting (n=33) and onset during non-fasting months (n=129).
- Analysis included monthly case counts, age, gender, and distribution of CVST cases.
Main Results:
- The mean number of CVST diagnoses during fasting months (5.5) was significantly higher than during non-fasting months (1.95).
- A statistically significant increase in CVST events was observed during Ramadan compared to other months (p=0.000).
Conclusions:
- Fasting appears to increase the frequency of cerebral venous and sinus thrombosis.
- This finding contrasts with studies on arterial stroke and requires further research.
- Individuals with hypercoagulable states or on oral contraceptives may be at higher risk during fasting.
Objective:
To determine whether fasting would affect the frequency of cerebral venous and sinus thrombosis compared to other months.
Methods:
All patients (n=162) with cerebral venous and sinus thrombosis admitted to three neurological centers from 2001 to 2006 in the Isfahan City were included in this study. Patients were divided into two groups according to the month of onset of cerebral venous and sinus thrombosis. The first group included patients with cerebral venous sinus thrombosis that occurred while fasting (n=33) and the second group was composed of patients with onset in other months, while not fasting (n=129). We evaluated the number of cases per month and compared ages, gender and the distribution of new cases during fasting versus non-fasting months.
Results:
From 2001 to 2006, the mean number of patients' diagnosis during fasting month was 5.5 versus mean number of patients during all other non-fasting months that was 1.95. The analysis showed a significantly increased frequency of cerebral venous sinus thrombosis events in Ramadan compared to other months (p=0.000).
Conclusions:
Our findings indicate that fasting increases frequency of cerebral venous and sinus thrombosis. These findings are inconsistent with other reported studies on arterial stroke and need to be confirmed by other studies. It seems that healthy people have no problem with regard to cerebral venous and sinus thrombosis while fasting, but susceptible persons, such as those with hypercoagulable states and women who take oral contraceptive pills, may be at increased risk.
